Abstract

The S³²–S³⁴ isotope exchange between sulphur dioxide and 100% sulphuric acid has been studied over the temperature range 200° to 400 °C. Equilibrium constants of 1.014, 1.011, and 1.008 at 205°, 300°, and 400 °C. respectively have been found, favoring the S³⁴ in the sulphuric acid. These results agree reasonably well with theoretical calculations made for the sulphur isotope exchange between sulphate ion and sulphur dioxide.
